Thermal measurement location

Thermal measurement location – top view

The thermal curves provided are based upon measurements made in TDK Innoveta’s experimental test setup that is described in the Thermal Management section. Due to the large number of variables in system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application. The critical component should be thermo- coupled and monitored, and should not exceed the temperature limit specified in the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact otherwise significant measurement errors may result.

iQM Series specifications

The TDK iQM Series represents a significant advancement in the realm of power inductors, catering specifically to applications that demand high efficiency and reliability. Designed for use in a variety of devices, including smartphones, tablets, and power supply systems, the iQM Series is tailored to meet the rigorous demands of modern electronics.

One of the standout features of the iQM Series is its compact size. The inductors are designed to maximize performance while minimizing space, making them ideal for applications where every millimeter counts. This compact design is achieved without compromising on performance, offering high inductance values that are essential for stable operation in power conversion circuits.

TDK has integrated innovative materials in the iQM inductors, utilizing a composite magnetic core that enhances energy efficiency and thermal performance. This ensures that the inductors operate effectively even at higher currents, reducing losses associated with heat generation. As a result, the iQM Series boasts a low DC resistance, contributing to improved overall system efficiency and enabling reliable operation in demanding environments.

Another notable characteristic of the iQM Series is its broad range of inductance values, which allows designers to select the most suitable inductor for their specific application requirements. This adaptability, combined with a wide operating temperature range, enables the iQM inductors to function efficiently in various climatic conditions and across different electronic devices.

Furthermore, the iQM Series is designed with a focus on minimizing noise. Advanced construction techniques have been employed to reduce electromagnetic interference, which is crucial for maintaining signal integrity in high-frequency applications. This makes the iQM Series particularly well-suited for power management circuits used in applications like DC-DC converters and power supply solutions.

The iQM Series also boasts impressive saturation current ratings, allowing for reliable performance even in peak current scenarios. This feature is essential for applications where transient loads can cause inductors to experience higher than normal currents. The ability to handle such conditions without saturating ensures longer device life and better performance under stress.

In summary, the TDK iQM Series of power inductors stands out due to its compact design, high efficiency, versatile inductance values, and effective noise reduction features. These qualities make iQM inductors an excellent choice for engineers looking to enhance their power management circuits in today's technologically advanced devices. With TDK's commitment to innovation and quality, the iQM Series is set to play a vital role in the future of electronics.
